This list, which is used by the LocalScheduler to allocate OPPORTUNISTIC containers, is sorted on the Nodes free capacity (queue length / wait time). > Unfortunately, the LocalScheduler stores this list in a HashMap thereby losing the sort order. > The trivial fix would be to replace the HashMap with a LinkedHashMap which retains the insertion order. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: yarn-issues-help@hadoop.apache.org
